18GHz Solution: Overview

• A compact external synthesizer is used as an LO to bring signals up to 18GHz down to a frequency range that is measureable by the native V93000 PSRF tester

• With FE24 card and PSRF 8GHz measurement solution this 18GHz module extends measurements to 18GHz

– We can measure CW or modulated signals to 18GHz

– Our prototype was validated with connectorized components



13

18GHz Solution: Synthesizer

• Foundation of this solution is Hittite HMC-C070 synthesizer

• Typical output power of +21dBm

• Capable of driving two mixers with a 2-way power splitter (6dB loss).

• Connects to 10MHz BNC on test head

• Controlled by SPI commands from standard SmarTest UTM



14

18GHz Solution: Block Diagram

• The 18 GHz solution is an external module (load board solution)

• To reduce cost, one synthesizer is shared between two sites

18GHz Solution: Performance

• Synth set to 10.5GHz, RF signal power (from Agilent E8257D sig gen) varied with freq. and power (top axis)

• Very linear over power range -30dBm to -90dBm• Measurable to -90dBm with very good linearity

17

18GHz Solution: Calibration

• Advantest will build these as hermetically sealed modules with factory calibration on an EEPROM with no further calibration needed

• Reduce burden of calibration for the end user

• Has slightly reduced accuracy compared to user-based calibration

• Eliminates need to have power meters and rack equipment on test floor

• Performance results indicate that calibration will be relatively easy to implement due to linearity of conversion loss

• The power supply and RF module are built to attach as a UDI anti-pogo assembly on one standard tester utility block



18

18GHz Solution: DC Supply Overview

• The V93000 5V Utility supply is used to generate three (3) separate voltages to power the synthesizer used with the 18GHz measurement module

• To keep tester costs down, we want to avoid using DPS resources

• Required power• Synthesizer pin VD1, 3.6V@125mA

• Synthesizer pin VD2, 20V@25mA

• Synthesizer pin VD3, 6.5V@375mA

• This is accomplished with 3 circuits

• All connected to the V93000 UP5V supplies• UP5V powers up when DUT board is docked

• All on same power supply UDI module

18GHz Solution: DC Supply Learnings

• HMC-C070 contains LT1764 LDOs on 3.6V and 6.5V inputs

– Hittite did this allow the user to apply a simple 12V to both inputs

– Problem is that this would lead to additional heat dissipation

– HMC-C070 already generates a lot of heat

– Approach we took was to have regulation and conversion on the separate DC supply board and supply exactly the required voltages to the HMC-C070

• Grounding– Multiple signal and power grounds: UGND, RF-GND, D-GND, PS-GND,

10MHz REFOUT BNC shield (tester chassis GND)

– RF-GND, D-GND and PS-GND’s are connected at HMC-C070

– 10MHz REFOUT is isolated from the rest with DC block transformer

• We can produce a UDI power supply and 18GHz extension module for less than $3k

• UDI

– Lowers cost of DUT fixtures

– Extends performance of standard ATE instruments

– UDI allows rapid prototyping and fast bring up for HSIO, RF and complex MX

reference boards

– Compatible with our standard docking and electrical interfaces

• 18GHz RF Solution– Available in 2015 as a packaged UDI module solution

• We also do a DUT board based connectorized version

– Key learnings from building the DC supply for the 18GHz solution• Base for RF module, EEPROM calibration support, ground management, UDI base

– Results indicate that calibration will be relatively easy to implement due to linearity of conversion loss

• Harmonic Measurement (HM) module– One board eliminates four (4) wideband directional couplers

– HM has same performance at <10% of the cost of traditional couplers

– Working on UDI anti-pogo version for 4 sites

– Evaluating higher frequency versions for additional applications• Higher power, modulated signals, fast signal switching
